Metallics JG5HC32 Bolts 1/2-13 X 1-3/4 G5 Hxbt St-zn (Jar 50)

It's a 1/2-13 bolt, meaning 1/2 inch nominal diameter with 13 threads per inch, which is standard UNC coarse thread. Any 1/2-13 UNC nut or tapped hole will take it. Measured thread major diameter runs 0.4930 to 0.5000 inch, and threads are made to ASME B18.2.1-2012.

Yes, and that's the intended use for the JG5HC32. It's a medium carbon steel cap screw, heat treated, with 105,000 psi minimum tensile and yield strength and a hardness of Rockwell C19-30. That's the normal spec for motor mounting, machinery bolting, and automotive or truck repair work. For higher-preload or high-fatigue structural joints, step up to a Grade 8 fastener instead.

Metallics lists the JG5HC32 as both Buy American compliant and ARRA compliant. Country of origin is recorded as multiple, so if your specification demands documentation for a specific mill or country on a federal contract, request the certification with the order.

Across-flats width measures 0.736 to 0.750 inch, so a 3/4 inch wrench or socket is the right fit. Corner-to-corner the head runs 0.840 to 0.866 inch, which matters if you're working inside a tight pocket or counterbore.

Length is measured from under the head to the tip, so the 1-3/4 inch body is your working length. Subtract the thickness of your nut and any washers from that to find how much material you can clamp and still have thread engagement through the nut. Metallics offers the G5HC and JG5HC series in other lengths and quantities by request if 1-3/4 inch comes up short.

The JG5HC32 is steel with a zinc finish, which handles indoor and sheltered mechanical room service well. Zinc plating is a sacrificial coating, not a marine-grade one, so for direct weather exposure, washdown areas, or coastal sites you want hot dip galvanized or stainless hardware instead.

It ships as a jar of 50 pieces, and 50 each is the order minimum, so the jar is the smallest unit. Total packed weight is 2,694 g. If you need a different count, Metallics lists other quantities in the G5HC and JG5HC series by request.

Yes. The jar contains 50 hex bolts only, no nuts and no washers. For a through-bolted joint you'll need matching 1/2-13 UNC hex nuts and, typically, hardened flat washers under the nut and head. If you're threading into a tapped hole in the machine base, the bolt alone plus a washer is all you need.

Material standard is AISI 1008 through 1026 carbon steel, heat treated to Grade 5 properties. Because the strength comes from heat treatment, don't weld on these or apply heat: you'll destroy the temper and lose the 105,000 psi rating. Same reason to avoid re-plating processes that involve baking or hot dipping.
